BOOK-LEAF FASTENER- SPECIFICATION forming part of Letters Patent No.753,976, dated March 8, 1904.

Application filed May 5, 1902. Serial No. 106,100. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM C. Gross, a citizen of the United States,residing at 1053 South Twenty-ninth avenue, Omaha, county of Douglas,and State of Nebraska,have invented certain new and useful Improvementsin Book- Leaf Fasteners; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to book-leaf fasteners; and it is the objectthereof to provide a fastener for loosely securing together a number ofpages of a book-such as a ledger or the likewhereby the said pages maybe turned as a unit and yet slide upon each other so that they may liesmooth and flat when the book is opened.

My invention consists in providing a book havinga slot extending throughall the leaves thereof and in combination therewith a two part fastener,one of said parts having tongues thereon adapted to pass through theslotted leaves of the book and into openings in the other part of thefastener, and in providing an opening in the latter fastener into whichthe protruding ends of the tongues may be turned, thereby securingtogether the two parts of the fastener and presenting a smooth andfinished surface.

In the accompanying drawings, Figure 1 is a perspective view of thefemale member of my fastener. Fig. 2 is a similar view of the malemember thereof. Fig. 3 is a similar view of the two parts fittedtogether and ready to be fastened by turning over the protruding ends ofthe tongues on the male member, and Fig. 4 is an enlarged view of aportion of a book having my fastener in use thereon, the same beingshown as broken through the slot in the leaves thereof in order to moreclearly show the underlying parts.

In carrying out my invention I provide a book having the slots 1 throughthe leaves thereof, as shown in Fig. 4.

The fastener comprises the female member 2, having the opening 3 in thecentral part thereof, and the slots 4 4 on each side of the centralopening, and the male member 5, having the tongues 0 0, formed thereonby mak ing two parallel longitudinally-extending cuts through the saidmember, another cut joining the longitudinal cuts and turning up thetongues so formed to a position perpendicular to the face of the saidmember, as shown.

The parts of the fastener are made, preferably, by stamping from sheetmetal. The proportionate size of the two members is such that thetongues c c on the member 5 are adapted to pass through the slots 4 4 inthe member 2, as shown in Fig. 3.

The fastener is particularly adapted for use with ledgers,account-books, and the like for cutting out dead or unused mattertherein by securing together a number of leaves thereof, so that thesame may be turned as a unit,

thereby obviating the necessity of continually turning over leavescontaining unused matter.

To use the fastener, the tongues 0 0 of the member 5 are passed upthrough the slots 1 in the leaves desired to be fastened together. Themember 2is then placed over the top of the slots 1, so that the tongues0 0 protrude through the slots 4 4, and the protruding ends of thetongues are then turned over into the opening 3 in the member 2 andextend into the slot 1 in the book-leaves, as shown in Fig. 4. It willbe noted that by this method of fastening together the leaves the samemay slip on each other between the two parts of the fastener and whenthe .bookis opened lie smoothly without bulging or buckling.

Now having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is

In a book-leaf fastener, and in combination with a book having slots inthe leaves thereof, a male member, a female member, substantiallyrectangular tongues on said male member, slots in said female memberthrough which the tongues are adapted to be passed, and an opening insaid female member between the the said members so as to lie flat whenthe said slots into which opening the ends of the book is opened.tongues may be turned and extend into the slot Signed in the presence oftwo witnesses.
